Following yesterday's Jelly Bean AOSP invasion, the HSPA+ Galaxy Nexus is now receiving the release build 4.1.1 (JRO03C) of Jelly Bean. That's indeed great news, but since the rollout is usually staggered, not all phones are allowed to receive it the second it's out there. If you're rooted or have an unlocked bootloader, why not just bypass the line and flash the update manually? I just did, and it took only a few minutes.

Our I/O Nexus 7s just received update notifications that a new software build is available for download - this is very likely the final retail build users will see when they receive their devices.

While a "changelog" of sorts pops up with the update notification, it's stock dialogue from a full-on Jelly Bean upgrade, not something specific to this particular update for the Nexus 7. More than likely, this OTA just irons out some bugs and turns off some unnecessary data logging and pre-release testing tweaks.
